To all whom it may concern."

Be it known that I, MaRsrrALL l iNIGHT THArnn, a citizen of the United States, and a resident of Edgemont, in the county of Fall River and State of South Dakota, have invented certainnew and useful lmprovements in Vaporizers, of which the following is a specification.

My present invention relates generally to internal combustion motors and more particularly toheating means therefor, whose function is to warm up andlimber the motor when cold and the object of my invention is to provide a simple comparatively inexpensive apparatus of this nature, whlch will not interfere in any way with the normal operation of the motor when once warmed up and which will be readily accessible, and easily perform its intended functions previous to starting.

It is a well known fact that internal combustion motors, particularly automobile motors are difiicult to start after standing and becoming chilled, and that the major reason for this. difficulty. arises from the congealed lubricating oil in the cylinders,

resulting in stiffening the action of the motor and so impairing compression as to prevent effective action in drawing in the propercharges of gas.. p p

The difficulty referred to also results from insuilicient {vaporization of the gas mixture i 1 pass to the working cylinders.

and. it is the further obj ect of my invention to provide meanswhereby external combus tion may be developed and the products thereof sucked directly into the working; cylinders. through the intakepipe so as to alleviate the conditions bringing about difficult starting both as to the lubricating oil and thegasmixturesfl o I therefore propose to slot the intakepipe of a motor and provide means forming a fuel chamber so located with respect to the slot as that the products of combustion of fuel. oil in. thechamber may be drawn into the intake pipe I and from thence into the working cylinder so as to liquefy the congealed lubricating oil and at the same time heat the intake pipe through which the combustible. gas mixture will subsequently invention also proposes the means formingtthe fuel oil. chamber shall at the same time be so located with respect to the slot of the intake. pipe as to avoid the danger of influx. of the fuel oil itself into the intake pipe, and contemplates the provision of a cover or closure for the fuel. oil chamber by ineans of which ingress of air into the intake pipe slot may be prevented during normal operation of the motor.

With the above in mind, my invention will be better understood from the following description of several forms thereof, shown in the accompanying drawings, to which the description refers. In these drawings which form a part of this speci fication,

Figure l is a front elevation illustrating my invention integrally formed and applied in connection with a motor intake pipe,

i Fig. 2 is a side view thereof,

. l lg. 3 1s a sectional plan view,

Referring now to these drawings and particularly to Figs. 1 to 4t inclusive, my invention proposes the provision of a motor intake pipe generally indicatedat 10 with a transverse slot 11 through. its wall and extending partially therearound, this slot being inclined with respect to a right angle and being continued in inclined relation through an enlargement 12 which extends partially around the pipe 10 for at least the length of the slot 11. Below the slot 11, pipe 10 has an outstanding horizontal flange 13 which constitutes the base of a fuel oil chamber 14 having along its outer edge an upstanding flange 15, forming the chamber wall. a p p It will thus be noted that the fuel oil chamber M is of arcuate shape. extending asit does partially around the pipe 10, and

entirely below the level of the upper outer bustion from the chamber 14,. without danger of influx of the fuel oil into the in take pipe 10.

Above the plane of the chamber 14 is a an outer depending flange 19 which exter ed by pivot bolts 18 to diametrically opposite; points of the pipe 10. This cover-has nally lapsthe upper edge of the flange or wall '15 of the fuel oil chamber and hasa'n inner "arcuate flange 20 which abuts a cooperating flange 21 of thepipe enlargement 1.2 so that the cover may be readily closed in ai'r tight relationon the fuel oil chamber and held by a set screw 22 Which works instance through the upper enlargement 12* of an inner wall 23 of the chamber.

This-inner wall which is curved to fit the contour of' the pipe lQf, has at its opposite endsupper andlower apertured ears 24 to receive clamping bolts or screws 25 extending also through the ears 26 at the opposite endsof thepipe embracingstraps 2Tshown particularly, in Fig. 6, so as to thus hold the fuel oil chamber forming means in proper position in connection with the pipe 10 and in the desired location relative to v the pipe slot 11*.

In this form the cover 16? which formed like thecover '16 of the construction of Figs; 1 tolinclusive' is hinged at -18 to the upper side portions of the inner wall 23 instead of directly to the pipe as in the former case;

In Fig. 7 I have sliownmy invention as applied inthe, length of the intakepipe be- 1 tween sections 10 fand 10and inthe nature 1 of a plate 28 disposed and clamped between the adjacent ends of these sections, plate 28 having a bore alining with the pipe bores and thus forming in effect a part of the ini I take ipe; ,Plate 28 has a'slot 29 which in 7 this instance projects vertically through an upperextension 30 ofthe plate and terminateswithi-nthe extreme upper'po rtion of a lateral enlargement 3l of extension 30 1 which enlargement forms a liquid fuel chamber In this construction a cover 7 33 ,-is hingedly connected directly to the upperend of extension 30-so as to coverlthe entire upp'e'rend of chamber :32, and ha-s a connectmgscrew'34 for engagement in an opening '85 in the outer wall of the cha n;

b'erifThe liquid fuel-chamber in this instance, like the liquid fuel chambers formed according to the "previously described con- --structions, may have an inner, absorbent member 36 stationarily held by a screw 37, which will hold a quantity' of liquidwfuel.

It is'obvious that all of the forms of ;con-

struction serve the same function as regards the delivery of products of combustion upon ignition of a quantity of hydrocarbon fuel within the liquid fuel chambers through the slot of the intake pipe and into the intake pipe for passage under the suction of the motor through its intake valves and into its working cylinders as indicated by the arrows in'Fig. 7. For this purpose the crank shaft of the motor is turned over by hand with the throttle valve closed and the entrance of the products of the combustion will serve-to quickly and effectively liquefy the congealed lubricating oil so as to enable the motor to promptly reach its normal efficiency as regards compression in the workin cylinders. Thus by turning over the crank shaft but a very few times, the motor will have reached the stage where it can effectively suck in its own charge, and the cover of the liquid fuel chamber can then be closed which will serve to damp out the flames and the throttle valve may then be opened afterthe cover is secured inairtight relation by the means previously described.

It is also to be noted that during the feed- ,ing of products of combustion of the fuel chamber to the working cylinders, the intake pipe will itself be heated so as to bring about enicient vaporization of the gas and in this way all of the parts will be advantageously affected in the interest of quick, eflicient starting no matter how coldv the motor may have previously been.
